The father's height usually affects the child, while the mother determines the child's fat and thin to a greater extent. Compare yourself with your parents if you don't believe me! Why is this truth? Let's explain it from a genetic point of view. First, absolute genetic skin color: people have no choice. It always follows the natural law of parents' "neutral" color. For example, parents with dark skin will never have children with white skin; If one side is white and the other side is black, most children will be given a "neutral" skin color that is neither white nor black after being "averaged" in the embryo, but there are also cases that are more biased to one side. Jaw: it's a dominant inheritance, so you can't "discuss". "Image" makes you helpless. For example, even if either parent has a prominent chin, children often have similar chins without exception, which is somewhat bizarre. Double eyelids: it is also an "absolute" inheritance. Interestingly, most of the father's double eyelids will be left to the children. Some children are born with a single eyelid, and when they grow up, they will "fill" the double eyelids like his father. In addition, big eyes, big earlobes, high nose and long eyelashes are the most characteristic inheritance that can be obtained from parents when the five senses are inherited. Second, hereditary obesity has a probability of more than half: it will make children have a 53% chance of getting fat. If one parent is obese, the probability of children being obese will drop to 40%. This shows that about half of being fat can be determined by human factors. Therefore, parents can make their posture symmetrical through reasonable diet and adequate exercise.
